I like the tones and colours, very natural.. However, I think your NNP is a touch out.. Also, it would not take much to fix up your nadir footprints with floors like that, even without a nadir image...

Add your images into APG 3.5 and detect.. In the detected panel you will see a drop down icon to export the Papywizard..

Name that to what you want.. Now use the Papywizard plugin and use your xml and images... This will detect auto.. Stop that and make sure the colour correction is turned off.. Now detect.. and render to about 4000 at 96dpi.. so you can send me a smaller file.. Use this.. https://www.wetransfer.com/# and send to dps@westnet.com.au

I will first make sure I can fix your nadir using a macro.. I assume you have Photoshop...

Your nadir will tell me a lot about your NNP.. I might be able to tell you which way to move it to correct it...

If you do not understand the above, just send me the RAW images used in one pano....

Don´t care too much about the Nadir. If you want to get rid of your tripod-legs:Drag your equirectangular image to the KRPano droplet "convert sphere to cube". You get 6 cubefaces. Take the "down" face and retouch the tripod legs as well as the Nadir hole by using the clone-tool in Photoshop of familiar app. That should take you no more than about five minutes in your case.After having retouched the Nadir drag all teh six cubefaces in one to the droplet "convert cube to sphere" - you get your equirectangular image with Nadir.
